Nexperia announced a new generation of in-vehicle network (IVN) protection diodes that offer a higher surge current, greater ESD robustness and a significant improvement in ESD clamping performance. The new AEC-Q101 qualified PESDxIVN series of surface mount devices is optimized for the latest generation of CAN, LIN, and FlexRay transceivers.

The new parts are drop-in replacement for legacy devices, available in familiar SOT23, SOD323 and SOT323 packages. However the new parts deliver higher performance. For example, PESD2IVN24-T parts deliver a 30 kV ESD robustness (up from 23 kV on the legacy PESD1CAN), an improved surge current of 3.5 A and much better clamping of 42 V at 3.5 A (was 70 V at 3 A). Other parameters remain constant or slightly better. The PESD1IVN27-A offers the same improvement in ESD robustness with a lower (=better) clamping voltage compared to the legacy PESD1LIN.

Commented Nexperia’s Marketing Manager Automotive André Dressler: “In modern vehicles there is an increasing amount of data exchange and the electronic content is growing in functionality and complexity, therefore effective ESD protection solutions are imperative. Nexperia has brought on-line a massive capacity increase for ESD diodes in order to guarantee a secure chain, and provide customers with peace of mind that they are protecting the electronics in their vehicles with high-performance, rugged and efficient devices.”
